Peach Tree, &#39;Burpeachfortytwo&#39;

ABSTRACT

A new and distinct variety of peach tree (Prunus persica), which is denominated varietally as ‘Burpeachfortytwo’, and which produces an attractively colored white-fleshed, clingstone peach which is mature for harvesting and shipment approximately September 5 to September 10 under the ecological conditions prevailing in the San Joaquin Valley of central California.

Botanical designation: ‘Prunus persica’.

Varietal denomination: ‘Burpeachfortytwo’.

BACKGROUND OF THE NEW VARIETY

The present variety of peach tree resulted from an on-going program of fruit and nut tree breeding. The purpose of this program is to improve the commercial quality of deciduous fruit and nut varieties, and rootstocks, by creating and releasing promising selections of Prunus, Malus, Punica, and Juglans species. To this end we make both controlled and hybrid cross pollinations each year in order to produce seedling populations from which improved progenies are evaluated and selected.

The seedling, ‘Burpeachfortytwo’ was originated by us, and selected from a population of seedlings growing in our experimental orchards which are located near Fowler, Calif. The seedlings, grown on their own roots, were derived from planting seed of an open pollinated seedling which was identified as, ‘A40.005’, (unpatented), and which further produces a yellow-fleshed, acidic fleshed peach. The pollen parent of this open pollinated seedling is known and unnamed, (unpatented), and produces a white-fleshed, clingstone, low acid nectarine. The resulting fruit was collected from the female parent (‘A40.005’) at a mature stage, and then seeds were extracted in September of 1998. After a period of stratification, the seed was placed in the greenhouse, by population, and then field planted for tree establishment, and ultimately to exhibit fruit for evaluation. One peach seedling which produced white-fleshed fruit, and which further is the present variety, exhibited especially desirable characteristics, and was then designated as ‘E63.008’. This seedling was marked for subsequent observation. After the 2001 fruiting season, the new variety of peach tree was selected for advanced evaluation, and repropagation.

ASEXUAL REPRODUCTION

Asexual reproduction of this new and distinct variety of peach tree was accomplished by budding the new peach tree onto ‘Nemaguard’ Rootstock (un-patented). This was performed by us in our employer's experimental orchard which is located near Fowler, Calif. Subsequent evaluations of these asexually reproduced plants have shown those asexual reproductions run true to the original tree. All characteristics of the original tree, and its fruit, were established, and appear to be transmitted through these succeeding asexual propagations.

SUMMARY OF VARIETY

‘Burpeachfortytwo’ is a new, novel, and distinct variety of peach tree. The present, new variety is a regular, and productive, bearer of relatively large, firm, white-fleshed, low acid, and clingstone fruit which have a very good flavor, and eating qualities. This new peach tree has what is considered to be a medium chilling requirement of approximately 650 hours. Further, the present, new variety produces relatively uniformly sized fruit throughout the tree's canopy. In addition to the foregoing, the fruit of the new peach also appears to have what are considered to be good handling and shipping qualities. The ‘Burpeachfortytwo’ peach tree bears fruit which are typically ripe for commercial harvesting and shipment on approximately September 5 to September 10 under the ecological conditions prevailing in the San Joaquin Valley of central California.

In relative comparison to the ‘Snow King’ peach tree (U.S. Plant Pat. No. 8,415), which is the closest known variety, the new variety of peach tree bears fruit of a more rounded and less elongated shape in general and a less pronounced apex. Further, the present, new variety is distinguishable from the ‘Snow King’ peach tree in view of its fruit, which has a higher percentage of reddish blush on the surface of its skin, whereas the ‘Snow King’ peach tree produces fruit having a lower percentage of reddish blush on the surface of its skin. Still further, the present, new variety is distinguishable from the ‘Snow King’ peach tree in view of its fruit, which is a clingstone, whereas the ‘Snow King’ peach tree produces fruit having a freestone.

In relative comparison to the unnamed, and unpatented seed parent ‘A40.005’, the current variety is easily and clearly distinguishable because it produces fruit having a white flesh, whereas the seed parent produces fruit have a yellow flesh characteristic. Moreover, the current variety of peach produces fruit having a low acidity, whereas the seed parent produces fruit having high malic acid levels. In relative comparison to the unnamed, and unpatented, pollen parent, the current variety is easily and clearly distinguishable because it is a peach, whereas the pollen parent is a nectarine.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of peach tree, the following has been observed during the tenth fruiting season, and under the ecological conditions prevailing at the orchards of the assignee which are located near the town of Fowler, county of Fresno, state of California. All major color code designations are by reference to the R.H.S. Colour Chart (Royal Horticultural Society, Fourth Edition, 2001) provided by The Royal Horticultural Society of Great Britain. Common color names are also occasionally used.

-   Tree:     -   -   Size.—Generally considered medium to large in its growth             pattern, as compared to other common commercial peach             cultivars ripening in the late season of maturity. The tree             of the present variety was pruned to a height of             approximately 270.0 cm to about 310.0 cm at commercial             maturity.         -   Width.—On average, about 285.0 cm.         -   Vigor.—Considered to have a medium vigor. The present peach             tree variety grew from about 170.0 cm to about 180.0 cm, in             height, during the first growing season. The new variety was             pruned to a height of approximately 150.0 cm during the             first dormant season, and primary scaffolds were then             selected for the desired tree structure.         -   Productivity.—Considered to be productive. Fruit set varies             from more than the desired crop load, to levels higher than             desired amounts, when the new variety is grown in a suitable             horticultural zone, and under appropriate commercial nursery             conditions. The fruit set is spaced by thinning to develop             the remaining fruit into the desired market-sized fruit. The             number of the fruit set varies with the prevailing climatic             conditions, and the cultural practices employed.         -   Fruit bearing.—Considered to be regular. Fruit set has been             more than adequate during the previous years of observation,             and thinning was necessary during the past 17 years on both             the original seedling and on subsequent asexually reproduced             trees.         -   Tree form.—Considered to be upright, and pruned into a vase             shape.         -   Density.—Considered to be moderately dense. It has been             discovered that pruning the branches from the center of the             tree to obtain a resulting vase shape allows for enhanced             air movement, and appropriate amounts of sunlight to improve             fruit color, and renewal of fruiting wood throughout the             tree.         -   Hardiness.—The present tree was grown and evaluated in USDA             Hardiness Zone 9. The calculated winter chilling             requirements of the new tree is approximately 650 hours at a             temperature below 7.0 degrees C. The present variety is             considered to be hardy under typical central San Joaquin             Valley climatic conditions. -   Trunk:     -   -   Diameter.—On average, about 25.5 cm in diameter when             measured at approximately 15.24 cm above the soil level.             This measurement was taken at the end of the 17th growing             season.         -   Bark texture.—Considered to be moderately rough, with folds             of papery scarfskin being present. Since bark development,             and coloration, change with advancing tree age, this             characteristic varies with the tree vigor, age, and regional             conditions. Therefore, this is not a dependable descriptor             of the new variety.         -   Lenticels.—Numerous flat, oval lenticels are present. The             lenticels range in size from approximately 4.0 mm to about             7.0 mm in width, and between approximately 1.0 mm to about             2.0 mm in height. The development and size of the trunk             lenticels can be influenced, to some degree, by the ambient             growing conditions, and are not, necessarily, a dependable             characteristic of this variety. As trees of this variety             mature, lenticels are present, but they are generally             covered by increasing layers of cork (mature bark) and             therefore become less apparent.         -   Lenticel color.—Considered to be an orange brown, (RHS             Greyed-Orange Group 164 B).         -   Bark coloration.—Variable, but it is generally considered to             be a greyed brown, (RHS Grey-Brown Group N199 B). This bark             description was taken from trees in their seventh leaf which             have ruptured the scarf skin, and which also have developed             bark furrowing which is much more typical of the bark of             older trees. It should be noted that the coloration of the             bark is influenced, and varies, as the smoother, darker,             background color approaches other bark features such as the             lenticels, and the initial fissures which form a feature of             the scarf skin development. -   Branches:     -   -   Size.—Considered to be medium to large for the species.         -   Diameter.—Considered to be average for the species. The             branches have a diameter of about 13.0 cm when measured             during the 10th year after grafting.         -   Flowering shoot thickness.—On average, about 5.0 mm to about             7.0 mm on annual wood.         -   Surface texture.—Considered to be average, and appearing             relatively smooth but with more furrowing on wood which is             several years old.         -   Crotch angles.—Primary branches are considered to be             variable, and are usually growing at an angle of about 43 to             about 55 degrees when measured from a horizontal plane. This             particular characteristic can vary due to the influence of             the assorted ecological conditions, and the cultural             practices which are being utilized.         -   Current season shoots.—Surface texture: Substantially             glabrous.         -   Internode length.—On average, about 2.4 cm.         -   Color of mature branches.—Grey brown, (RHS Greyed-Orange             Group 166 C).         -   Current season's shoots.—Color: Medium-light green, (RHS             Yellow-Green Group 146 C). The color of new shoot tips is             considered to be a bright and shiny green (RHS Yellow-Green             Group 146 D). The vegetative shoot color can be             significantly influenced by plant nutrition, irrigation             practices, and exposure to sunlight, and therefore should             not be considered a consistent botanical characteristic of             this new variety. -   Leaves:     -   -   Size.—Considered to be medium for the species. Leaf             measurements have been taken from vigorous, upright,             current-season growth, at approximately mid-shoot. It should             be understood that the leaf size is often influenced by             prevailing growing conditions, quality of sunlight, and the             location of the leaf within the tree canopy. For this             reason, leaf sizes can vary significantly based upon the             ambient, and other cultural factors listed above, and are             not typically considered a dependable botanical descriptor.         -   Leaf length.—On average, about 153.0 to about 160.0 mm.         -   Leaf width.—On average, about 32.0 to about 35.0 mm.         -   Leaf base-shape.—The leaves generally exhibit equal marginal             symmetry relative to the leaf longitudinal axis.         -   Leaf form.—Lanceolate.         -   Leaf tip form.—Acuminate.         -   Leaf color.—Upper Leaf Surface: Dark yellowed green,             (approximately RHS Yellow-Green Group 147 A).         -   Leaf texture.—Upper Leaf Surface: Glabrous. Lower Leaf             Surface: Glabrous.         -   Leaf color.—Lower Leaf Surface: Light to medium green,             (approximately RHS Yellow-Green Group 146 A).         -   Leaf venation.—Pinnately veined.         -   Mid-vein.—Color: Considered a light yellow, (approximately             RHS Yellow-Green Group 154 D) in the early to mid-period of             the growing season.         -   Leaf margins.—Gently undulating.         -   Form.—Considered finely crenate.         -   Uniformity.—Considered generally uniform.         -   Leaf petioles.—Form: Considered to be canaliculated, and             having a more pronounced trough when viewed from the dorsal             aspect. The petiole margin is considered to be rounded when             viewed from the ventral aspect. Length: On average, about             7.0 to about 10.0 mm. Considered to be medium to small for             the species. Diameter: On average, about 1.5 to about             2.0 mm. Color: Yellow green, (approximately RHS Yellow-Green             Group 144 A). Texture: Virtually glaborous. Strength:             Considered durable for species until senescence.         -   Leaf glands.—Size: Considered small for the species; on             average, about 1.5 mm in length; and on average, about 1.0             mm in height. Number: Generally, one, and less commonly two,             glands appear per marginal side. Observations of more than             two glands per marginal side are very uncommon. Type: Glands             located at the base of the leaf are predominantly reniform             in shape. Color: Considered a medium-dark brown,             approximately (RHS Brown Group N199 B). Typically, the             coloration of the glands darkens, and occasionally begins to             desiccate during the mid-late growing season.         -   Leaf stipules.—Size: Considered medium for this species.             Number: Typically, 2 per leaf bud, and up to 6 per shoot             tip. Form: Lanceolate, and having a serrated marginal edge.             Color: Green, (approximately RHS Green Group N138 A) when             young, but graduating to a brown color, (approximately RHS             Greyed-Orange Group 165 A) with advancing senescence. The             leaf stipules are generally considered to be early             deciduous. -   Flower buds:     -   -   Hardiness.—No winter injury (bud death) has been noted             during the last several years of observation in the central             San Joaquin Valley. The new variety of peach tree has not             been intentionally subjected to drought, cold or heat             stress, and therefore this information is not available.         -   Flower bud.—Size: Variable, and dependent on the state of             maturity. The flower buds as described were observed             approximately 7 days prior to bloom. Length: On average,             about 16.0 mm. Diameter: On average, about 7.0 mm. Surface             Texture: Pubescent. Orientation: Considered appressed, but             appearing less so as the blossoms near opening.         -   Bud scale color.—Approximately RHS Greyed-Purple N186 C. -   Flowers:     -   -   Date of first bloom.—Observed on Mar. 1, 2017. The blooming             time is considered average in relative comparison to other             commercial peach cultivars grown in the central San Joaquin             Valley. The date of full bloom was observed on Mar. 5, 2017.             The date of full bloom varies slightly with climatic             conditions, and prevailing cultural practices.         -   Duration of bloom.—On average, about 8 or more days. This             characteristic varies slightly with the prevailing climatic             conditions.         -   Flower class.—Considered to be a perfect flower, complete             and perigynous.         -   Flower type.—Considered to be rosette (showy).         -   Flower size.—Considered to be medium to large for the             species. The flower diameter, at full bloom, is, on average,             about 45.0 to 50.0 mm.         -   Bloom quantity.—Considered to be abundant.         -   Flower bud density.—Generally considered to be dense.         -   Flower bud frequency.—Generally, two flower buds appear per             node. Occasionally one flower bud per node is observed.         -   Petal size.—Generally considered medium to large for the             species. Petal Length: On average, about 24.5 to 26.5 mm.             Petal Width: On average, about 18.0 to 21.0 mm.         -   Petal form.—Considered broadly ovate.         -   Petal count.—Nearly always 5.         -   Petal texture.—Upper Petal Texture: Gently glaborous. Lower             Petal Texture: Very gently glaborous.         -   Petal color.—Considered a light pink at the popcorn stage,             (RHS Red-Purple Group 65 D), and darkening with advanced             senescence, and the exposure of sunlight, to a medium-dark             pink, (RHS Red-Purple 63 C).         -   Fragrance.—Considered to be slight.         -   Petal claw.—Form: Considered to be ovate, generally medium             to small, and more elongated and relatively narrower when             compared to other varieties. Length: On average, about 7.0             to 9.0 mm. Width: On average, about 4.5 to 6.0 mm.         -   Petal margins.—Generally considered to be variable, from             nearly smooth to moderately undulate, and ruffled,             especially apically.         -   Petal apex.—Often the petal margin exhibits a shallow and             wide recess at tip. Width: On average, about 1.5 to 3.0 mm.             Depth: On average, about 1.0 to 2.0 mm.         -   Flower pedicel.—Length: Considered to be medium to long with             a length of, on average, about 1.5 to about 3.0 mm.             Diameter: On average, about 1.5 mm. Color: A medium-brown,             approximately (RHS Grey-Brown Group N199 D) depending upon             the pedicel, fruit maturity, and the timing of the visual             observation. Strength: Tenacious. Considered to be average             for the species.         -   Floral nectaries.—Color: Considered a pale green             (approximately RHS Yellow-Green Group 154 B).         -   Calyx.—Surface Texture: Generally glabrous. Color: A dull             orange red, (approximately RHS Greyed-Orange Group N167 B).         -   Sepals.—Upper Surface Texture: Pubescent. Lower Surface             Texture: Glabrous. Number: 5 sepals. Size: Considered to be             average. Sepal Length: On average, about 4.5 to 7.0 mm.             Sepal Width: On average, about 5.0 to 6.5 mm. Sepal Shape:             Generally obovate. Sepal Margin: Considered to be smooth and             entire. Sepal Color: A dull grey-red (approximately RHS             Greyed-Red Group 178 B).         -   Anthers.—Generally: Considered to be average in size. Color:             Orange when viewed dorsally, and prior to dehiscence,             (approximately RHS Greyed-Orange Group 168 B). Position             Relative to Stigma: Generally, the stigma is superior to the             anthers by approximately 1.0-2.0 mm.         -   Pollen production.—Pollen is abundant, and has a yellow             color, (approximately RHS Yellow-Orange Group 21 B).         -   Fertility.—Self-fertile.         -   Filaments.—Size: On average, about 16.5 to 19.5 mm in             length. Color: Considered white to a pinkish-white, (RHS Red             Purple Group 65 D).         -   Pistil.—Number: Usually one, and only occasionally more than             one. Generally: Considered to be medium to large in size.             Length: On average, about 16.5 to about 19.5 mm in length             including the ovary. Considered to be long for the species.             Color: Considered a very pale green, (approximately RHS             Yellow-Green Group 149 D). Surface Texture: Considered to be             pubescent. Position Relative to Petals: At flower maturity             the stamens grow to be superior to the petals. -   Fruit:     -   -   Maturity when described.—Firm ripe condition (shipping             ripe).         -   Date of first picking.—Approximately Sep. 2, 2017.         -   Date of last picking.—Sep. 10, 2017. The date of harvest can             vary with the prevailing climatic conditions, volume of             fruit on the tree, and the current climatic and cultural             practices which are employed.         -   Size.—Considered to be large, and very uniform.         -   Average cheek diameter.—On average, about 72.0 to about 79.0             mm.         -   Average axial diameter.—On average, about 73.0 to about 78.0             mm.         -   Typical weight.—On average, about 275.0 grams. This             characteristic is quite dependent upon the prevailing             cultural practices and growing conditions, and therefore is             not particularly distinctive of the new variety.         -   Fruit form.—Generally — Considered to be globose. The fruit             is generally very uniform in symmetry.         -   Mucron tip.—Absent.         -   Fruit suture.—No stitching exists along the suture line.         -   Suture.—Color: Generally, the fruit appears blushed to the             same degree as the skin, (approximately RHS Orange-Red Group             N34 A).         -   Ventral surface.—Form: Considered to be even, and uniform in             appearance, when it is viewed from the lateral, sutural             plane.         -   Apex.—Shape: Rounded.         -   Base.—Shape: Generally smooth.         -   Stem cavity.—Generally: It extends in a rounded circular             form which is generally considered to be uniform. The stem             cavity is rounded but slightly extended toward the suture.             The depth of the stem cavity is, on average, about 8.0 mm to             about 10.0 mm. The width of the stem cavity is, on average,             about 30.0 mm. The length of the stem cavity, when measured             in the suturial plane, on average, is about 55.0 mm.         -   Fruit skin.—Thickness: Considered to be medium in thickness,             and tenacious to the flesh. Surface Texture: Short, fine,             and pubescent. The pubescence is moderately abundant. Taste:             Non-astringent. Tendency to crack: Not observed in the             previous years of observation and evaluation.         -   Fruit skin color.—Blush Color: Generally speaking, a red             blush exists on a majority of the skin of the fruit             (approximately RHS Orange-Red Group N34 A), and is more             typically present on the portions of the fruit facing the             sunlight. The blush of the fruit typically covers             approximately 65%-85% of the fruit skin surface. The             percentage of the blush on the fruit skin surface can vary,             and is generally dependent upon the influences of the             current season's environmental conditions, the fruit's             exposure to direct sunlight, the specific fruit maturity,             and also the prevailing ecological and cultural conditions             under which the fruit was grown.         -   Ground color.—A creamy white, (approximately RHS             Yellow-White Group 158 C). The ground color of the fruit can             vary significantly based upon the maturity of the fruit when             this measurement is taken, and generally gains a lighter,             and less green cast, with higher maturity.         -   Fruit glossiness.—Fruit is not considered to be glossy.         -   Fruit stem.—Size: Considered medium in length, on average,             about 6.0 to about 8.0 mm. Diameter: On average, about 2.0             to about 3.0 mm. Color: Pale yellow-green, (approximately             RHS Yellow-Green Group N144 C).         -   Fruit flesh.—Ripening: Considered to be even. Texture: Firm,             juicy, and dense. Considered to be firm, yet non-melting.             Fibers: Considered to be absent or weak. Aroma: Considered             to be light. Eating Quality: Considered to be very good.             Flavor: Considered balanced with sweetness and acidity.             Juice Production: Moderate. Brix: About 15.0 to 18.0             degrees. This characteristic varies slightly with the number             of fruit per tree, the maturity of fruit when harvested, the             prevailing cultural practices, and the ambient climatic             conditions. Acidity: Considered to be low. Approximately 0.3             titratable acidity. Acid levels assayed from fruit flesh can             vary with fruit maturity, sunlight exposure, climatic, and             other regional and cultural influences. Flesh Color:             Considered to be a cream white, (approximately RHS Yellow             Group 13 C), often exhibiting pigmentation of red radiating             from the stone (approximately RHS Greyed-Red Group 179 A). -   Stone:     -   -   Type.—Considered a clingstone.         -   Size.—Considered to be medium for the species. The stone             size varies significantly depending upon the tree vigor, the             crop load, and the prevailing growing and cultural             conditions under which the tree was grown.         -   Length.—On average, about 29.0 to about 31.0 mm.         -   Width.—On average, about 22.0 to about 26.0 mm.         -   Diameter.—On average, about 18.0 to about 20.0 mm.         -   Form.—Roughly obovate.         -   Stone base.—Shape: Shortly attenuate.         -   Apex.—Shape: The stone exhibits a slight to prominently             acute apex.         -   Stone surface.—Surface Texture: Considered to be irregularly             furrowed toward the apex. Further, more pitting exists in             the mid-portion of the stone (laterally), and is more common             toward the base. Ridges: Ridging is generally more             prominent, and is usually oriented parallel, and laterally             relative to the ventral and dorsal margins. Ventral Edge:             The ventral edge is generally considered to be troughed with             three substantial grooves that converge apically. Dorsal             Edge — Shape: Generally considered to be even. The folds of             the surface ridges appearing on the external margins often             end gently along the suture.         -   Stone color.—The color of a mature, dry stone is generally             considered a dull brown, approximately (RHS Greyed-Orange             Group 177 A). The stone color can vary considerably in view             of how recently the fruit has ripened, the degree of             oxidation which has taken place, and any blanching which has             occurred due to exposure of the stone to sunlight.         -   Tendency to split.—Splitting has not been noted.         -   Kernel.—Length: On average, about 19.0 to about 21.0 mm.             Width: On average, about 13.0 to about 15.0 mm. Thickness:             On average, about 5.0 to about 6.0 mm. Size: The kernel is             considered medium in size. Form: Considered generally ovoid.             Kernel Surface Texture: The kernel pellicle is considered to             be slightly pubescent. Color: A dark tan (RHS Greyed-Orange             Group 165 B).         -   Use.—The present variety ‘Burpeachfortytwo’ is considered to             be a peach tree of the late season of maturity, and which             produces fruit which are considered to be firm, attractively             colored, and which are useful for both local and long             distance shipping.         -   Keeping quality.—Considered to be excellent for the species.             The fruit of the present variety has stored well for periods             of up to 35 days after harvest at 1.0 degree Celsius.         -   Shipping quality.—Considered to be good for the species. The             fruit of the new peach tree variety showed minimal bruising             of the flesh or skin damage after being subjected to normal             harvesting and packing procedures.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety has not             been intentionally tested to expose or detect any             susceptibilities or resistances to any known plant, fruit             diseases, insect, frost, winter injury, or other             environmental factors. Although the new variety of peach             tree possesses the described characteristics when grown             under the ecological conditions prevailing near Fowler,             Calif., in the central part of the San Joaquin Valley of             California, it should be understood that variations of the             usual magnitude, and characteristics incident to changes in             growing conditions, fertilization, nutrition, pruning, pest             control, frost, climatic variables and changes in             horticultural management are to be expected. 

Having thus described and illustrated our new variety of peach tree, what we claim is new, and desire to secure by plant Letters Patent is:
 1. A new distinct variety of peach tree, substantially as illustrated and described, and which is characterized principally as to novelty by producing an attractively colored white-fleshed, clingstone peach which is mature for harvesting and shipment approximately September 5 to September 10 under the ecological conditions prevailing in the San Joaquin Valley of central California.
